Morales identified the victims as Molson Coors Brewing Co. employees ranging in age from 33 to 57.

The five men include an electrician, a Navy veteran, a father of two small children, a fisherman and a grandfather.

Molson Coors chief executive officer Gavin Hattersley says employees are grieving for the five who were lost, saying they were part of the fabric of the company and they will be missed.

"Five families, six families actually are grieving and will be grieving because of this horrific act of this individual,” Milwaukee Mayor Tom Barrett said earlier in the day.

Morales said police are still investigating a motive.

Police searched Ferrill’s home on Milwaukee’s north side as they hunted for clues about why an employee at one of the nation’s largest breweries gunned down five co-workers before taking his own.

More than 1,000 employees were working on the sprawling campus, when they began receiving text and email alerts from the company about an active shooter.

“We are here on the scene of another American tragedy. Another senseless American tragedy ... and I hate to say that it is in our backyard once again. This is the 11th mass shooting in our state since 2004,” said Lt. Gov. Mandela Barnes, D - Wisconsin.
